An Introduction to Numerical Modeling of Composite Plate Shear Walls / Concrete Filled (C-PSW/CF)
Composite plate shear walls / concrete filled (C-PSW/CF) are being used as the lateral force resisting system for high rise buildings in the US and other countries. Individual walls are considered for low- to mid-rise buildings (less than 15 stories) and coupled composite core walls are considered for mid- to high-rise building (15 - 30 stories). When used as individual composite shear walls, the lateral resistance of C-PSW/CF is governed by the in-plane flexure and shear behavior, which is influenced by steel yielding, local buckling, concrete confinement, and the tie bar reinforcement ratio. When used as coupled composite shear walls, the lateral resistance of C-PSW/CF is governed by their behavior under a combination of axial force, inplane flexure, and shear. This behavior is influenced by the same parameters mentioned above along with the axial load level.
